One of the most interesting magnetic devices known to man is a magnetic force field that can be created by a rare earth metal such as iron, cobalt or titanium. The first rare earth metal to be used was based on the rare earth metal samarium and later on the transition metal cadmium. Also referred to as the smalto-cobalt (SMCo) magnetic material, it was initially developed in the late 1960s and proved to be more efficient than earlier permanent magnetic materials. Since then, a number of other rare earth metals have been used in manufacturing magnetic items.

All the metals that have high density can be used to make permanent magnets due to their high number of electrical repulsion and attraction properties. Many of these alloys can be customized to take on any shape desired. These properties make them ideal for use in applications requiring a lot of strength and lightweight. Some of these alloys, such as cobalt, titanium and steel, are already in wide use.

Other alloys are more brittle than others. These include the cobalt alloys, which are said to be stronger and lighter than iron. Some of the other more brittle ones include titanium and nickel. There have also been rare-earth magnets developed which show promise in applications other than electricity-related. For example, strong magnets are now being used to build miniature magnets to power remote control boats.

There are many different types of rare earths that have different attractive magnetic properties. Tin, aluminium, copper, nickel and phosphorus all have different strengths and other characteristics that magnet designers need to keep in mind. They can also produce different kinds of ions. The way in which these ions are produced is important, too. Certain types of rare earths produce negative ions, while others produce positive ions. It is the properties of the ions produced that set them apart.

Alloys with particularly high porosity can produce strong electromagnetic fields. Strongly bonding two rare earths together can produce a type of magnetic field that is much smaller than the electrical one, but is strong enough to induce proton attraction. This is the basis of some of the most efficient motors used today. Such motors work by using the magnetic field to drive a series of electromagnets and to strengthen this, the magnets are placed in a particular orientation.

The most common examples of these motors include those made using nDFeb magnets. These magnets, which are a spinel, have a particular orientation which allows them to respond in a certain way to a common, well-known electric current. The magnetic force produced by these nDFeb magnets high magnetic strength is powerful enough to lift an automobile or an aircraft out of the air. In addition to their large size, they can also move very quickly, thanks to their lightweight construction. They are designed for use in applications where a very strong magnetic field is needed, such as in space or underwater.

The most efficient motors using rare earth magnets are those that use solid iron as the main material. There are many advantages to these motors, the most obvious of which is that they are capable of sustaining a strong magnetic field for a long period of time. These alloys have the additional advantage of being able to conduct electricity. The motors built from these alloys can power anything, whether it is a vehicle, a ship or a house: they are robust and durable, and their ability to support a strong magnetism makes them suitable for all sorts of applications.

In addition to using rare earth metals for the construction of their motor, companies producing these motors also use other alloys, in order to increase their strength and their longevity. Many alloys feature properties called boron, which enable them to be stronger than most common iron. Many other alloys feature the properties of tungsten, which is a very strong and ductile metal. Most of these alloys feature a unique electrostatic charge, which allows them to maintain a very strong electrical charge when exposed to an alternating current of electricity. These alloys are particularly well suited to applications where power consumption is very low, or where they need to support a strong magnetic field for a long time.
